1. Product Introduction of Ultrafiltration Membrane Equipment
As a professional ultrafiltration membrane equipment manufacturer, we take modified PVDF organic hollow fiber membrane and ceramic membrane as the core filtering medium, and integrate membrane modules, stainless steel frame, booster pump, backwashing unit, chemical dosing cleaning device and PLC automatic control cabinet into integrated finished equipment. All products are finished by unified assembly, pressure testing and running debugging before delivery, realizing plug-and-play installation on the user’s project site.
Our product portfolio forms a complete product gradient to satisfy differentiated customer demands. Conventional industrial water treatment projects can select our general Ultrafiltration equipment with fixed standard specifications, which has low cost and stable performance for daily circulating water filtration and general wastewater recovery. For projects with special water quality, site space and water volume requirements, we support drawing customization through the Custom Ultrafiltration System service, adjusting membrane quantity, pipeline material and system flow according to on-site actual working conditions. Mass standardized projects such as water plants and large factory water workshops can adopt the batch-produced Professional Ultrafiltration Machine, which is produced by assembly line to shorten delivery cycle and guarantee unified product quality. For high organic pollution, high turbidity wastewater working conditions, the anti-pollution Organic Membrane Ultrafiltration System with reinforced hydrophilic membrane filaments is matched to reduce membrane fouling frequency and cut operation maintenance costs.
The shell and pipeline of conventional equipment adopt SUS304 stainless steel; SUS316L stainless steel and anti-corrosion lining are optional for corrosive wastewater environments. The core ultrafiltration membrane supports two mainstream materials: organic PVDF membrane and inorganic ceramic membrane. The whole system supports unattended automatic operation, with pressure difference interlock protection, automatic backwashing and timing chemical cleaning functions, effectively lowering manual operation difficulty for end users. As a direct manufacturer without intermediate dealers, we can provide customers with product optimization, spare parts supply and after-sales technical support in the whole service cycle.
2. Working Principle of Ultrafiltration Membrane Equipment
Ultrafiltration membrane equipment relies on low pressure as driving force to achieve physical separation via the microporous structure on the membrane wall, adopting cross-flow filtration mode in actual operation, divided into three working states: normal water production, automatic backwashing and chemical cleaning.
2.1 Normal Filtration & Water Production
Raw water is pressurized by the feed pump and evenly enters each ultrafiltration membrane component. The membrane pore size is controlled at 0.01~0.1μm. Water molecules and tiny soluble ions pass through the membrane pores to form qualified permeate water for production use. Suspended solids, colloids, bacteria, algae and macromolecular organic matter are intercepted on the inner surface of the hollow fiber membrane. Most raw water flows tangentially along the membrane surface to form cross-flow scouring flow, which continuously washes pollutant sediments and maintains stable membrane flux during long-time operation.
2.2 Automatic Backwashing Process
With the accumulation of intercepted pollutants, the pressure difference between the raw water side and produced water side gradually rises. When reaching the preset threshold value, the PLC system automatically starts the backwashing program. Clean produced water is used for reverse flushing from the water producing side to the feed side to peel off surface dirt and discharge sewage out of the system. The backwashing time is short and will not affect the continuous water supply of the overall system.
2.3 Regular Chemical Cleaning
Long-term operation will cause organic fouling, biological slime and inorganic scale inside membrane pores. The supporting acid & alkali dosing system is used for circulating immersion cleaning to remove stubborn pollutants thoroughly, restore the original flux of membrane elements and extend the service life of core ultrafiltration membranes.
